Isaiah Washington is wrong. A lot has changed...
When democrats (the party of the KKK, White Citizen's Council, George Wallace and Bull Conner) took over the black community with their lies, the first horrible change they made was to install new 'leaders'.
The old leaders of the black community had brought blacks through slavery, Jim Crow, and the horrors of the KKK with families intact - and a divorce rate lower than that of white families. Black men were valued in the community as men of God and heads of their families.
Democrats changed all of that...
Democrats moved in and upended the black community - bringing in new leaders - corrupt democrat poverty pimps as 'leaders' - men who assisted with breaking up the black family and destroying established neighborhoods with urban renewal etc.
So yeah, the democrat party has done a lot to the black community - almost all of it bad...
I once heard someone state that desegregation was bad for blacks because while segregated, they were forced to shop at black businesses which helped to support a burgeoning middle class and the values that went with it. No doubt LBJ and the democrats did most of the damage, but I wonder how much influence desegregation had given that everything in life has a downside.
